Thundelarra confirms Red Bore as VHMS Setting
THE DRILL SERGEANT: Thundelarra (ASX-THX) has confirmed the Gossan and Impaler prospects, part of the company’s 90 per cent-owned Red Bore project, located in the Doolgunna region of Western Australia, have potential to host volcanic-hosted massive sulphide (VHMS) mineralisation.
The company said it had based this conclusion on a review of geological and geochemical data from diamond holes TRBD010 – 012 not previously reported.
Thundelarra said the drilling program the review was based on had four main objectives:
To improve understanding, and to test for extensions, of the mineralisation at the Impaler prospect by diamond drilling with the hope that core samples would provide clearer geological information from the zones where earlier reverse circulation drilling had encountered broken ground;
To improve the understanding of the mineralisation at depth at the Gossan prospect;
To re-visit the Jaspilite target to the south-east of Gossan that was previously tested by RC; and
To re-visit a target south of Gossan, located close to the southern tenement boundary.
“Geological logging of the holes identified sections that displayed the peperitic textures that are considered to represent the right setting for the occurrence of VHMS (Volcanic-Hosted Massive Sulphide) mineralisation,” Thundelarra said in its ASX announcement.
“Relevant sections were submitted for multi-element geochemical analysis, the results of which confirmed the presence of anomalous values for pathfinder elements that indicate a potential VHMS setting.”
Thundelarra is confident the presence of peperitic and other textures recorded in the drill cores at both Impaler and Gossan provide further geological evidence the package of Interfingered volcaniclastic sediments, basalts, plus the dolerites, represents a geological setting with potential to host VHMS mineralisation.
“This in turn provided the commercial reason to commit shareholder funds to laboratory multi-element assays to provide greater accuracy than the readings obtained to date from hand-held XRF Analyser,” the company explained.
“These two diamond holes at Impaler were also significant in that primary copper mineralisation displaying representative VHMS-style characteristics was encountered.
“This is the first recorded occurrence of primary VHMS-style mineralisation at Impaler.”
